摘要:

Fifteen Japanese igneous reference rocks have been analyzed by X‐ray fluorescence spectrometry and instrumental neutron activation analysis for major and trace elements. Agreement between measured and accepted values is generally favourable with, however, several exceptions. Small systematic discrepancies are noted for MgO, Na2O, Sr, The, Eu, and Lu, which are likely the result of differences in calibration and/or analytical techniques. Zn generally shows poor agreement, suggesting that the rocks are not well characterized for this elemen

摘要:

The preparation and study of the two rock reference samples, Quartz Diorite SKD‐1 and Sviatonossite SSv‐1, are described, along with mineralogical and petrographic features. After its homogeneity studies, the two samples were analysed by seventy‐five former USSR laboratories in the framework of an interlaboratory analytical program. The two samples have been certified respectively for 41 and 39 major, minor and trace elements; additionally, values are proposed for about 20 trace elements. The compiled data on the two samples are presented as an Appendix. Both the samples, processed in about 280 kg, form now part of the set of eight magmatic rock reference samples prepared by the Institute of Geochemistry in Ir

摘要:

This study reports the results of thirteen rare earth elements (REE) in sixteen geochemical reference samples. The analytical procedure involved dissolution of a whole rock or mineral separate, spiking with Tm, and separation of the REE using a simple ion‐exchange chromatography procedure. The resulting REE solutions were analysed by ICP‐MS. The results are compared with literature values. The agreement between our data and recommended or ID‐TIMS values is very favorable. The precision of the technique is better than 5% (2) for all th
